The band apologized for the cancellation and expressed hope for the political situation there to be resolved and for them to return to play in the future.

The statement reads: "Due to the ongoing political crisis in the region, we are sad to report that we have decided to cancel our shows in Moscow, St Petersburg and Kiev this summer.

"Ticket refunds are available at the point of purchase. We remain hopeful of coming to play for you in the future and we sincerely hope this current instability resolves in a positive, democratic and peaceful way. Take care of yourselves and we hope to see you soon."
